Can I use piston-mcp with the public Piston API?

As of February 15, 2026, the public Piston API requires an authorization token, so piston-mcp will not work with the public instance without one.

Which MCP clients are compatible with piston-mcp?

Claude Desktop is explicitly supported with a provided example configuration.

How do I install piston-mcp?

You can run piston-mcp locally via the uv tool without cloning the repository.

Quick Install

Automated & IDE Setup

Copy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.

One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.

Manual Client & Custom JSON ConfigExpand JSON ▾

No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for alvii147/piston-mcp, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.

Overview

This MCP server connects large language models to the Piston code execution engine, allowing them to run code snippets remotely. It requires no configuration when run with the uv tool and includes a ready-to-use example configuration for Claude Desktop. Note that as of February 15, 2026, Piston's public API requires an authorization token, so this server no longer works with the public Piston instance without one.

Use cases

Execute code snippets in multiple programming languages via LLMs

Integrate code execution capabilities into MCP clients like Claude Desktop

Test and debug code dynamically through AI agents

Run code remotely without local environment setup

Key features

Supports remote code execution through Piston API

Zero-configuration setup using uv tool

Includes example configuration for Claude Desktop client

Supports multiple programming languages via Piston

Piston MCP Server

piston-mcp is an MCP server that allows LLMs to connect to and execute code using Piston.

[!WARNING] As of Feb 15, 2026, Piston API is no longer publicly available and requires an authorization token. This means piston-mcp will no longer work with the publicly hosted instance of Piston.

Installation

You can try out piston-mcp locally without cloning it.

Install uv

To try out piston-mcp you'll need to install uv:

bash

# On MacOS and Linux
curl -LsSf https://astral.sh/uv/install.sh | sh
# On Windows
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Install MCP Client

You will also need to download an MCP client to connect to piston-mcp, such as Claude Desktop.

Update MCP Client Configuration

Update the MCP client's configuration with the following configuration to connect to piston-mcp:

config.json

{
  "mcpServers": {
    "piston": {
      "command": "uv",
      "args": [
        "tool",
        "run",
        "--from",
        "git+https://github.com/alvii147/piston-mcp.git@main",
        "piston_mcp"
      ]
    }
  }
}

For Claude Desktop, the configuration file is usually found in:

bash

# On MacOS and Linux
~/Library/Application\ Support/Claude/claude_desktop_config.json
# On Windows
%APPDATA%\Claude\claude_desktop_config.json

Usage

Once you've followed the steps above, your MCP client should be able to run code for you:
